Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors and other biologically active compounds. Its structure allows for selective functionalization, making it valuable in medicinal chemistry for constructing complex heterocyclic systems. Commonly employed in cross-coupling reactions such as Suzuki or Heck reactions to build carbon-carbon bonds in drug discovery programs. Also utilized in the preparation of agrochemicals and functional materials where pyridine-based scaffolds are required. Its aldehyde group enables further derivatization, including conversion to alcohols, acids, or imines, expanding its utility in synthetic pathways.
